Sia Releases Triumphant New Track, ‘Unstoppable’

Pop powerhouse Sia is gearing up to drop her This Is Acting album next week (January 29), and she's just unveiled her latest, "Unstoppable."

"Unstoppable" follows in line with previous album tracks "Reaper" and "Bird Set Free." Its chorus is bolstering and triumphant, with soaring vocals and vaguely empowering lyrics rounding things out: "I'm unstoppable / I'm a Porsche with no brakes / I'm invincible / Yeah I win every single game." In other words, "Unstoppable" is everything you could possibly want in a pop song, something Sia knows all too well.

"I think I'm a good curator, so I know how to choose tracks that feel like they're anthemic, or that seem to have an uplifting quality in the chorus," she told Rolling Stone in December. "It really seems like the general public responds well to songs about salvation or overcoming something, or that everything’s going to be OK, or that things are fun."

She says her massive hits "Chandelier" and "Titanium" aren't particularly inspiring to her, though she recognizes that those songs do well with the Top 40 crowd: "[After] watching the PS22 choir sing 'Titanium' and then listening to the children being interviewed afterwards saying that it actually really impacted them — some of the kids were being bullied — I felt like I was jaded and cynical, and I felt like a bit of an asshole. I thought, 'Why don't you loosen up, you prick! This stuff that you think is cheesy is really impacting these kids around the world. Why don't you stop being so judgmental?'"
